IMPROVEMENT lN CAR-AXLE LUBRICATORS.

Specification forming part of Letters Patent No. 122,495, dated January2, 1872.

To all whom it may concern:

Be it known that I, JOHN S. SANSON, of Morrisania, in the county ofWestchester and State of New York, have invented a new and usefulImprovement in Lubricators for Car- Axles; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accom panying drawing forming part of thisspecification, and in which Figure 1 represents a vertical section, indirection of the length of the axle, of arailroadcar axle-box, showingthe one end of the axle in full, and with my improvement appliedthereto; Fig. 2, a transverse section of the same at the line 00 m inFig. 1; and Fig. 3, a horizontal section at the line 3/ y, with theaxleremoved.

Similar letters of reference indicate corresponding parts throughout theseveral figures of the drawing.

The one part of my invention relates to revolving lubricators, composedof a wheel arranged to bear up against the journal of the axle, andserving, as it is rotated by frictional contact therewith, to convey thelubricating material to the journal; and this part of the inventionconsists in a novel construction of said lubricator, including a pivotedsuspension of the wheel by means of a hanger to the rod or arm, by whichit is carried, said rod being also pivoted or hinged and controlled by aspring, likewise being properly steadied or dirooted to insure the wheelwhen in its place, being borne up against the journal and held in properrelation therewith to convey the lubricating material contained withinthe axlebox to the journal. By this construction every facility isafforded for insertion and removal of the lubricator within and from thebox, as ordinarily constructed; and when the axle is in its place, sothat the lubricator may be applied to railroad-car axle-boxes, as now inuse, as well as to new ones, and a perfect action, generally, isobtained. The invention also consists in a combined pad and wiper, ofnovel construction, for preventing the washing or working of thelubricating material along the axle beyond the journal and out of thebox, thereby contributing to the economy and efficiency of thelubricator.

Referring to the accompanying drawing, A

represents a railroad-car axle-box of ordinary construction, providedwith the usual outside or front-end lid I) and upper brass 0. B is theaxle, and d its journal within the box A. O is the lubricating-wheelarranged Within the box A, beneath the journal, and serving, as it isrotated by frictional contact with the latter, to

convey oil placed in the bottom of the box to the journal. This wheel iscarried by a hanger, D, pivoted beyond or above its center, on oppositesides, as at e e, to the inner jaw-like end of a main carrying arm orrod, E, the pivots e e occupying a transverse relation with the axis ofthe wheel and that of the car-axle, and preferably dropping loosely intobearings f f in the jaw-end of the rod or arm E. The outer end of thisrod or arm is pivoted or hinged in proximity to the front end of the boxA by means of a cross-pivot or pivots, g, fitted to work in a socket orrecess, h, formed in a claspplate, F, to provide for the adjustment ofthe Wheel 0 up to or against the journal. A spring, G, arranged around apin or projection, H, at tached to the clasp-plate F, serves, by itspressure against the under side of the arm E, to thus adjust or forcethe wheel up against the journal, and said pin or projection H, by itspassage through a slot, i, in the rod or arm E, further serves to steadyand direct said arm with its attached wheel.

By this construction, and more especially by the pivoted suspension ofthe wheel through its hanger, as at e e, which admits of the wheel beingswung so that its face is on a level, or thereabout, with the axial lineof the joint or pivots g of the arm E, every facility is afforded forthe entry and attachment of the lubricator within the box when the axleis in its place; likewise of its removal therefrom through the openingcovered by the lid b, even though the space between the outer collar ofthe axle and front end of the box be as contracted as it usually is.Thus the lubricator may be applied to axle-boxes now in use, and withoutdisturbing them or their axles, and when in place its action is perfect.

To prevent waste of the oil consequent upon its washing or being carriedout of the box along the axle beyond the journal by the lateral motionof the cars, I arrange within the box, at its back end, a combined padand wiper,

I, arranged to bear against the lower portion of the body of the axle inproximity to its journal, and composed in part of a plate, It, and

piece or pieces of felting l, or other suitable material, the sameserving to wipe off the oil after it has passed from the journal, andpreventing it from running along the axle, also returning it again tothe bottom of the box. To facilitate the entry of this pad and wiper andproper adjustment and retention of the same, the plate It has pivoted toit a wire bow or handle, m, whereby the device may be readily projectedthrough the opening covered by the lid I), and, by the fit of the bowedend of the handle 122 under the clasp-plate F, said pad and wiper issecurely held to its place; also, every facility afforded for itsremoval when required. By means of this pad and wiper the usual waste byleakage of oil, as hereinbefore'.

referred to, is avoided, and but a small quantity of oil in this boxwill suffice to keep the lubricator fully supplied, thereby doing awaywith many evils consequent upon the lubricator running short of oil.

What is here claimed, and desired to be secured by Letters Patent, is

1. The suspension of the lubricating-wheel G in a hanger, D, pivoted tothe hinged rod or arm E, and supported by the spring G and pin H,substantially as and for the purpose specified.

2. The combination of the pivoted or swinging rod E, the clasp-plate F,the spring G, the steadying pin or projection H, the pivoted swinginghanger D, and the wheel 0, the whole being arranged for operationessentially as and for the purposes herein set forth.

3. The pad and wiper I, composed of a plate, 70, and felting l, incombination with the hinged or pivoted bowed handle m for operationwithin the box A, substantially as described.
